Thanks! I had the same problem! I only took out the small power supply board at the side, so i could reach the joints with my soldering iron. Saved me a lot of time. I used some flux and new solder and the receiver is working perfect again!
Thank you! It worked. I pulled off the connector and one of the pins actually fell out. Soldered it back in and touched up the next one and it’s staying powered on now!
It started all of a sudden turned it on and bam it turned on & off by itself tried looking into default mode because I really don’t want to open it up so found no default mentioned in manuel so tried RU-vid and got you!!Thank You for taking the time to post most helpful!!
I had the same problem. I unplugged the small white HDMI power connector on the far left side (first plug in this video), then plugged it back in, and it worked. Try this before pulling out the HDMI board. It was a two-second fix.
Thanks a lot! I have the same problem. It started out sporadically, but now cycles constantly, so it sounds like it might well be the same root cause that you found. Will try your fix.
I pulled a Denon AV receiver out of the electronic recycle. I haven't powered it up yet but I have already studied up on common problems. This is very helpful and an easy fix if it has a problem like this. I have a stack of high end AV receivers from recycle, all but one is brain dead. I've started to strip a couple (amplifier boards out of a brain dead Onkyo power up and work, very promising and 90 watts with 110 volt split supply) but I might try to fix a couple. And I have to say, the "high end" (like Denon and Onkyo) aren't really built all that well, although Onkyo really has great features. Plus when they go brain dead (all but inevitable if you use them long enough) you have a $600 paperweight. I have a stack of 80s and 90s era stuff I fixed easy as pie. Pioneer, Fisher, Nakamichi , Luxman - all can be easily repaired and just replacing the electrolytic capacitors in a working unit gives you another 20 years of reliable service.
I am working on a similar Denon receiver with similar issue. In my case I believe there may actually be a bad component. I am puzzled by the board to board connectors. They appear to be latched together in some fashion and do not want to pull apart. I have been reluctant to apply too much force for fear of damaging the boards. Does anyone have some advice for separating the boards without breaking anything? A video showing how to disconnect the boards from each other would be great.
Hi! maybe you have some photos with the bord where audio cabel betwin preamp and amp connects? I need preouts from this reciever/ so there is two ways. solder it to connector on amp bord or? maybe there is a connector on bord ander hdmi bord .. I've read service manual.. so there is option B for preouts on that bord, but i don't know is thare a connector .
my denon avr x2100w is functioning normally due to an oversight I entered maintenance mode from there it switches on soon it goes out and starts and flashes the standby light, how do I revert this maintenance mode
Those are just pin type connectors. They literally just pop out. Lift up the top edge of the connector to release the locking tabs using a small flat screw driver or a plastic tool. Careful not to break the plastic. Only needs to be lifted very slightly. Connector should now easily slide apart. Might need a bit of pressure the first time. I'd suggest removing all the screws in the back that hold the HDMI board in place first (back of housing along HDMI ports). Careful reconnecting those pins so you don't bend them. Also try to pull that board back as straight as possible, again, so you don't bend the pins. Was a bit scary doing it the first time. Was sure I'd break something but it worked out fine. horrible design.
I wiped the top of my HDMI board down with rubbing alcohol and a q-tip, after it stopped going into protection mode and has been working smoothly since.
I have the same receiver with the same issue. It first started happening a couple of years ago and I read somewhere that there is a relay that gets flaky; I assume poor connections due to either dust or oxidation or (?). The quick and easy solution was to physically bounce the receiver, vigorously.This worked and the issue went away for months. Lately it only fixes it for a few days, and now daily. I have resorted to picking it up and sort of slamming it down. Of course this is not a solution so I will be pulling it out and taking it to my bench to check for bad solder, etc and for a relay to replace - as soon as my wife is finished watching her cooking shows ;)
@@bhadwamodi8294 ha! Yes but she watches a lot of cooking shows. I still haven't pulled the receiver out to troubleshoot it, I've only had to slam it about once a month.
Mr Ganesan i too had same problem (denon x2200 )switches on and NO AUDIO NO VIDEO, did you had a chance to repair it. please let me know londonsiva@gmail.com
Some of the Denon products had problems with the output transistors. With the parts and technology today, there is absolutely no excuse for that. It's very disappointing. That's why I keep my stack of vintage stuff in good working order. Easy to troubleshoot, easy to fix. If it's still working 30 years later, then they must have built it to last. If you can fix it at home, then I don't see a downside to that.
Hi Srijith Ramachandran, Can you please mention which location this capacitor located in SMPS Board. I have the same problem. Can you please provide the reference in the board.
